Water damage to natural history collections can result from both natural and human-caused environmental disasters. Floods can result in irreparable damage to scientific specimens, depending on the scale of the disaster, types of specimens affected, and availability of remediation resources. In April 2021, the mammal skeletal collection in the Biodiversity Research Collections (BRC) of the University of Connecticut (UConn) experienced a ceiling flood that affected 612 specimens. In this paper we detail all steps of our specimen rescue process and all materials and equipment we used to complete this remediation in an endeavor we termed “Operation Bone Rescue.” Because we were able to immediately respond to this emergency and implement a complete remediation plan, facilitated by funding from our university, we not only rescued all water-affected specimens, but also improved specimen storage and metadata. We highlight the holistic nature of this successful operation and the key roles played by personnel in the BRC, UConn Facilities Operations, Fire Department, and College of Liberal Arts and Sciences Dean's Office. A deep appreciation of the value of natural history collections is shared widely on our campus and resulted in the favorable outcomes of this complex, coordinated specimen rescue effort.

The ornithological collection of the National Fish and Wildlife Forensic Laboratory in Ashland, Oregon includes over 6,800 bird skin and loose feather specimens. These are essential reference material for the morphological identification of avian evidence in wildlife crime investigations by the U.S. Fish and Wildlife Service. In the summer of 2020, these specimens were moved from several locations and installed in a new building dedicated to the laboratory's bird, mammal, and herpetological collections. Following installation in the new building, a severe outbreak of mold was discovered in many of the cabinets containing bird specimens. This paper reports on the likely cause of the mold outbreak and the actions taken to control it, preserve the specimens, and prevent future outbreaks.

A growing number of domestic and international legal issues are confronting biodiversity collections, which require immediate access to information documenting the legal aspects of specimen ownership and restrictions regarding use. The Nagoya Protocol, which entered into force in 2014, established a legal framework for access and benefit-sharing of genetic resources and has notable implications for collecting, researchers working with specimens, and biodiversity collections. Herein, we discuss how this international protocol mandates operating changes within US biodiversity collections. Given the new legal landscape, it is clear that digital solutions for tracking records at all stages of a specimen's life cycle are needed. We outline how the Harvard Museum of Comparative Zoology (MCZ) has made changes to its procedures and museum-wide database, MCZbase (an independent instance of the Arctos collections management system), linking legal compliance documentation to specimens and transactions (i.e., accessions, loans). We used permits, certificates, and agreements associated with MCZ specimens accessioned in 2018 as a means to assess a new module created to track compliance documentation, a controlled vocabulary categorizing these documents, and the automatic linkages established among documentation, specimens, and transactions. While the emphasis of this work was a single year test case, its successful implementation may be informative to policies and collection management systems at other institutions.

We present a method for the cataloging and retrieval of frozen tissue samples stored in a −80°C freezer via image databasing of the samples using server software (PowerPoint) and digital photography. This method is an inexpensive, computer-guided, rapid retrieval technique for visually locating frozen tissue samples in collections. This approach increases retrieval efficiency and reduces sample integrity risk.

Inexpensive vacuum bags, designed to store fabrics and made from oxygen-barrier plastic, were repurposed as ambient temperature nitrogen chambers to neutralize pests on herbarium specimens. Combination t-test and ANCOVA results on data from oxygen-monitoring tablets indicated 0.1% anaerobia was maintained inside these bags for 39 days. Anaerobia below 0.3% oxygen maintained for up to 3 weeks deactivates insects, bacteria, and most molds. One or two small oxygen-absorber packets placed inside bags affected how quickly and reliably 0.1% anaerobia could be achieved and maintained. Three vs. six flushes with nitrogen had no statistically significant effect for achieving anaerobia.

The Museo de La Salle–Bogotá (MLS) houses biological specimens of which 30% (17,001 specimens) are stored in fluid (ethanol 70%). The collections have historical significance for documenting Colombian biodiversity and contain the oldest zoological specimens in the country. For these reasons, the curation and management of the specimens require special attention and endless vigilance. In this study we assessed the decrease in ethanol level in jars of the MLS fluid collections over a 3-year period from 2013 to 2016 and evaluated the relation between container and lid type and ethanol loss. We did not observe a relevant decrease in the percentage of ethanol levels during 2013–2016. However, the type of lid used influenced the amount of ethanol that evaporated; we found that the pressure and twist lids were more effective in maintaining the ethanol levels in the containers, since they have a pressurized rotation system that allows a more secure closure in contrast to the pressure cap, which does not prevent the evaporation of ethanol. Based on our evaluation, we suggest the use of pressure and twist closure caps or caps with a continuous thread closure type along with a tamper-evident seal between the jar mouth and the container cap to ensure a tight and secure seal for minimizing the risk of fluid loss and ensuring the preservation of fluid-fixed specimens of this historical collection.

There were more than 348 natural history collections and 179 medical collections in Germany compared with 68 natural history collections in France (Charon 2014). More than half of these have parts of the collections stored in fluids, and thus they will all use jars and will all face similar problems (e.g., regularly needing new jars and effectivemethods for sealing them). After 17 years of working with jars, moving wet collections, realizing the KUR-Projekt (Neuhaus et al. 2012), and conducting many workshops, I would like to give a short overview about future ideas and plans and a brief conclusion of my point of view. In most of the wet collections I have visited or worked with, such as the ones of the Museum für Naturkunde (MfN), the majority of the jars used are glass stopper jars (e.g., the Spider wet collection at theMfN shown in Fig. 1). However, such collections also contain a wide variety of other types of glass and plastic containers with a range of closures, including glass plates, plastic snap or screw-on lids, and jars sealed with Picein, an asphaltum– rubber compound (Simmons 2014). Some closures and containers are efficient and durable for the long-term preservation of specimens, and in the past 10 years, both soda glass with twist-off lids and borosilicate glass jars have been used. Yet the question always arises related to the management of these collections: which are the best? Is it preferable to actually use borosilicate glass jars, reputed to be effective but expensive, or is it enough to consider soda–lime twist-off glass jars, which are less expensive? To answer the question, it does not seem sufficient to consider only the price and availability of these containers. Other factors are important, including the need to ensure a proper seal, consideration of the jar contents, and the need for institutions to share resources. For more than 100 years, collection assistants, curators, and collectionmanagers have been dealing with jars and have developed a large pool of knowledge and experience. While there are existing networks to share this knowledge, such as the Society for the Preservation of Natural History Collections (SPNHC) wiki (https://spnhc.biowikifarm.net/wiki) or the Natural Sciences Collections Association (NatSCA) and Global Conservation Forum lists, they are not exclusively dedicated to issues related to fluid collections. The day-to-day management of a fluid collection requires special expertise and attention to detail. The people in charge of the conservation of these collections have their own knowledge and experience to draw on, but it is difficult to find this information in books or articles. Most of the time, this knowledge is exchanged with colleagues in the museum or sometimes with well-known colleagues in the field working in other museums around the world. Beyond this small group, it is difficult at the moment to share one’s own knowledge or to write articles detailing these facts. It is only in recent ye
德国有超过348个博物馆藏和179个医学馆藏，而法国有68个博物馆藏(Charon 2014)。其中一半以上将部分收集物储存在液体中，因此它们都将使用罐子，并且都将面临类似的问题(例如，定期需要新的罐子和有效的密封方法)。经过17年的罐子工作，移动湿收藏品，实现KUR-Projekt (Neuhaus et al. 2012)，并举办了许多研讨会，我想简要概述一下未来的想法和计划，并简要总结一下我的观点。在大多数湿收集我去过或共事,比如博物馆的皮毛Naturkunde (MfN),大多数使用的罐子是玻璃塞罐(如蜘蛛湿收集theMfN图1所示)。然而,这样的集合也包含各种各样的其他类型的玻璃和塑料容器的闭包,包括玻璃板、塑料吸附或用螺钉固定的盖子,并与Picein罐子密封,沥青-橡胶复合西蒙斯(2014)。一些瓶盖和容器对于标本的长期保存是有效和耐用的，在过去的10年里，有拧开盖子的苏打玻璃和硼硅玻璃罐都被使用了。然而，与这些集合的管理相关的问题总是出现:哪些是最好的?是使用硼硅玻璃罐更可取，它被认为是有效的，但昂贵的，还是考虑钠石灰扭转玻璃罐，它更便宜?要回答这个问题，仅仅考虑这些容器的价格和可用性似乎是不够的。其他因素也很重要，包括需要确保适当的密封，考虑罐子的内容，以及机构共享资源的需要。一百多年来，收藏助理、馆长和收藏经理一直在处理罐子，并积累了大量的知识和经验。虽然有现有的网络来分享这些知识，如自然历史藏品保护协会(SPNHC) wiki (https://spnhc.biowikifarm.net/wiki)或自然科学藏品协会(NatSCA)和全球保护论坛列表，但它们并不专门致力于与流体收藏相关的问题。液体收集的日常管理需要特殊的专业知识和对细节的关注。负责保护这些藏品的人有自己的知识和经验可以借鉴，但很难在书籍或文章中找到这些信息。大多数时候，这些知识是与博物馆的同事交流的，有时是与在世界其他博物馆工作的该领域的知名同事交流。除了这一小群人之外，目前很难分享自己的知识或撰写详细描述这些事实的文章。直到最近几年，我们才开始理解这些技术知识代表了什么，以及如果不维护这些知识库，我们可能会失去什么。管理流体收集的挑战凸显了以下需求

Conservation of the preserving medium is an essential element for the proper preservation of specimens in fluid collections. However, the preservatives can become chemically altered over time or be lost by processes such as evaporation. To combat such changes and properly care for and maintain immersed specimens, it is therefore necessary to know what preservative fluid was initially chosen and how its chemistry may have evolved with time. The present work explores the possibilities offered by Raman spectrometry for a rapid, nondestructive, noninvasive alternative to commonly employed chemical identification tests, which are often limited to the identification of simple fluids. In a first step, fluids were reconstituted and analyzed in small standard glass containers to evaluate the potential of the technique. Then we successfully applied the procedure to real cases and considered its possible use to estimate the concentration of ethanol and to detect small quantities of formaldehyde (down to 1%). The results demonstrate the power of this technique, which opens up new possibilities for the management of fluid collections.

The Museum of Anatomy and Embryology of the Université Libre de Bruxelles (ULB), part of the Laboratory of Anatomy, Biomechanics, and Organogenesis (LABO), was founded around 1838 by the anatomist and surgeon Louis Deroubaix (1813–1897) shortly after the ULB was established (Kinnaert and Louryan 2009, Louryan et al. 2010). Initially, the Museum of Anatomy and Embryology contained human specimens from the main old hospitals of Brussels. Further anatomical parts were gradually collected and dissected by successive teachers of human anatomy and their team thanks to a legal system of body donation. Since the museum’s inception, many bone and soft tissue dissections, preserved in liquid medium, have contributed to the enrichment of the collections for pedagogical purposes. Following the faculty of medicine, the museum’s geographical location has changed four times across Brussels, from the Charles de Lorraine’s palace in the city center to the present location on the periphery of the city in the university’s medical campus.

Resulting from faculty turnover and successive curators’ areas of interest, this museum diversified over time. Figure 1 displays a general overview of the museum, including fluid collections. Various plaster orwaxmodels (e.g.,His-Stegermodels, Tramond’s wax castings, and castings from the famous collection created by Seifert and Nicolas) were progressively added, as was teratological material. As an example, Figure 2 shows a three-dimensional CT scan reformation of a newborn (preserved in fluid) with severe aprosopia (complex and rare facial malformation) as well as pathological, anthropological, odontological, and comparative anatomy specimens. New dissections, many of which are plastinated, are regularly added to the collections, while most past acquisitions were made by incorporating other collections or private donations.

布鲁塞尔自由大学(ULB)解剖学和胚胎学博物馆是解剖学，生物力学和器官发生实验室(LABO)的一部分，在ULB成立后不久，解剖学家和外科医生Louis Deroubaix(1813-1897)于1838年左右成立(Kinnaert and Louryan 2009, Louryan et al. 2010)。最初，解剖学和胚胎学博物馆收藏了来自布鲁塞尔主要老医院的人体标本。由于遗体捐赠的法律制度，后来的人体解剖学老师和他们的团队逐渐收集和解剖了更多的解剖部位。自博物馆成立以来，许多骨骼和软组织解剖，保存在液体介质中，有助于丰富教学目的的收藏。继医学院之后，博物馆的地理位置在布鲁塞尔发生了四次变化，从市中心的查尔斯·德·洛林宫殿到现在位于城市外围的大学医学院校园。在一个单独的建筑里，有一个广泛的兽医骨骼收藏供学生使用。由于教师更替和连续策展人感兴趣的领域，这个博物馆随着时间的推移而多样化。图1显示了博物馆的总体概况，包括流体收藏。各种石膏或蜡模型(例如，他的斯蒂格模型，特拉蒙的蜡铸件，以及由塞弗特和尼古拉斯创作的著名系列的铸件)逐渐增加，畸形材料也逐渐增加。例如，图2显示了一个新生儿(保存在液体中)严重斜视(复杂而罕见的面部畸形)的三维CT扫描改造，以及病理、人类学、牙科学和比较解剖学标本。新的解剖，其中许多是塑化的，定期添加到收藏中，而过去的大多数收购是通过合并其他收藏或私人捐赠获得的。塑化材料提高了材料的节约，使教室内的交通更加方便。该博物馆目前收藏了大约1500件标本，包括液体保存的和干燥的材料，以及骨学教学收藏。解剖学和胚胎学博物馆是为了教学目的而建立的。因此，在解剖学和胚胎学课程中，大多数标本(液体保存或其他)都是用相机展示的。解剖学和胚胎学课程在博物馆旁边的一个房间里进行。此外，标本在解剖演示和实践会议中展示，或者使用医学成像文件和虚拟解剖解剖台。在学习过程中，从书本大小的纸质插图切换到三维图像是具有挑战性的。使用真实的解剖标本可以帮助学生，并允许他们，除其他事项外，观察结构的规模和纹理，以发展更深更广泛的知识。由于标本的使用可能导致损坏，每次从瓶中取出标本后，必须仔细监测标本的状况。维护标本需要定期更换
